Ape grabbing an awning (6)
I believe the answer is:
canopy
'awning' is the definition.
(thesaurus)
'ape grabbing an' is the wordplay.
'ape' becomes 'copy' ('copy' can be a synonym of 'ape').
'grabbing' is an insertion indicator.
'copy' placed around 'an' is 'CANOPY'.
(Other definitions for canopy that I've seen before include "Cloth covering" , "Pay Con badly for the covering" , "Covering over four-poster, etc" , "Roof-like awning" , "tester" .)
